preparation example Construction

[0038] In the preparation of the display panel, due to the large number of light-shielding structures 40, it is unavoidable that the vertical projection (first projection) of the light-shielding structure 40 on the plane where the substrate 20 is located and the vertical projection (first projection) of the light-emitting element 30 on the plane where the substrate 20 is located ( The second projection) partially overlaps, combining Figure 4-Figure 6 or the vertical projection (first projection) of the light-shielding structure 40 on the plane where the substrate 20 is located and the vertical projection (second projection) of the light-emitting element 30 on the plane where the substrate 20 is located completely overlap, combined Figure 4 , Figure 7-Figure 14 As shown, these two structures cause visually there is a black area when viewing the display panel, corresponding to the position of the light-shielding structure 40 , thereby affecting the display effect. To solve t...

Abstract

According to the display panel, a refraction structure is additionally arranged between a film layer where a light-emitting element is located and a film layer where a shading structure is located, the refraction structure comprises a first refraction structure and a second refraction structure, and the refractive index of the second refraction structure is larger than that of the first refraction structure; according to the principle that light enters the low-refractive-index material from the high-refractive-index material to be totally reflected to change the propagation direction of a light path, the light emitted by the light-emitting element is totally reflected on the interface of the first refraction structure and the second refraction structure and then reaches the position above the shading structure, and the propagation direction of the light path is changed. The display effect of the black area above the shading structure is weakened or even eliminated, and the display effect of the display panel is comprehensively improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people such as daily life and work, and has become an indispensable essential tool. [0003] In the existing electronic equipment, there is a problem that metal traces block the light-emitting area, resulting in a visual black area above the metal traces, which affects the display effect. Contents of the invention [0004] The present invention provides a display panel and a display device. By adding a refraction structure between the film layer where the light-emitting element is located and the film layer where the light-shielding structure is located, part of the light emitted by the l...
